This piece of metal gives me peace of mind. I work off a mayo stand and this makes my rinse cup a little more secure when i have to roll the stand. I wrap it with saran wrap and stick the 3oz cup in and it feels very stable. Easy to clean. My only criticism is the corners. They are not sharp to cut per say, but they are a little pointy. Be careful when placing it on a soft surface, like a tattoo bed so it wont cut any vinyl surfaces
